Exhibit 99.1

DESCRIPTION OF COMMON STOCK

We are authorized to issue up to 205,000,000 shares of capital stock, including 200,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share. As of August 14, 2015, we had 79,604,624 common shares and 95,100 shares of Series B Preferred Stock (as defined below) issued and outstanding.

On August 27, 2015, our stockholders approved a proposal to implement a reverse stock split at a ratio of any whole number between one-for-two and one-for-eight, as determined by our Board of Directors, at any time before August 27, 2016, if and as determined by our Board of Directors. Our Board of Directors has not yet implemented such a reverse stock split.

Common Stock

Each outstanding share of common stock entitles the holder to one vote, either in person or by proxy, on all matters submitted to a vote of stockholders, including the election of directors. There is no cumulative voting in the election of directors. All actions required or permitted to be taken by stockholders at an annual or special meeting of the stockholders must be effected at a duly called meeting, with a quorum present of a majority in voting power of the shares entitled to vote thereon. Stockholders may not take action by written consent. Special meetings of the stockholders may only be called by our Board of Directors acting pursuant to a resolution approved by the affirmative majority of the entire Board of Directors. As more fully described in our Certificate of Incorporation, holders of our common stock are not entitled to vote on certain Amendments to the Certificate of Incorporation related solely to our preferred stock.

Subject to preferences which may be applicable to any outstanding shares of preferred stock from time to time, holders of our common stock have equal ratable rights to such dividends as may be declared from time to time by our Board of Directors out of funds legally available therefor. In the event of any liquidation, dissolution or winding-up of our affairs, holders of common stock will be entitled to share ratably in our remaining assets after provision for payment of amounts owed to creditors and preferences applicable to any outstanding shares of preferred stock. All outstanding shares of common stock are fully paid and nonassessable. Holders of common stock do not have preemptive rights.

The rights, preferences and privileges of holders of common stock are subject to the rights of the holders of any outstanding shares of preferred stock.

Preferred Stock

Our Board of Directors is authorized to issue up to 5,000,000 shares of non-voting preferred stock, par value $0.001 per share, in one or more series, without stockholder approval. Our Board of Directors is authorized to determine, with respect to each such series: (i) the rate of dividends payable thereon; (ii) the price, terms and conditions on which shares may be redeemed; (iii) the amount payable upon shares in the event of involuntary liquidation; (iv) the amount payable upon shares in the event of voluntary liquidation; (v) sinking fund provisions for the redemption of shares; (vi) the terms and conditions on which shares may be converted, if any; and (vii) voting powers.

Each share of each series of preferred stock will be identical in all respects with all other shares of the same series. Preferred stock does not have preemptive rights.

Our Board of Directors previously established a series of preferred stock designated as Series B Convertible Preferred Stock (“Series B Preferred Stock”), comprising 400,000 shares of Preferred Stock, of which 95,100 shares remain outstanding as of August 14, 2015. Subject to superior rights of any other outstanding preferred stock from time to time, each outstanding share of Series B Preferred Stock is entitled to receive, in preference to the common stock, annual cumulative dividends equal to $0.25 per share per annum from the date of issuance, which shall accrue, whether or not declared. At the time shares of Series B Preferred Stock are converted into common shares, accrued and unpaid dividends will be paid in cash or with common shares. In the event we elect to pay dividends with common shares, the shares issued will be valued at $0.50 per share. Series B Preferred Stock does not have any voting rights. In the event of liquidation, each share of Series B Preferred Stock is entitled to receive, in preference to the common stock, a liquidation payment equal to $5.00 per share plus any accrued and unpaid dividends. If there are insufficient funds to permit full payment, the assets legally available for distribution will be distributed pro rata among the holders of the Series B Preferred Stock.

Each share of Series B Preferred Stock may be converted into ten fully paid shares of common stock at the option of a holder as long as we have sufficient authorized and unissued shares of common stock available. The conversion rate may be adjusted in the event of a reverse stock split, merger or reorganization.

Article and Bylaw Provisions with Possible Anti-Takeover Effects

As described above, our Board of Directors is authorized to designate and issue shares of preferred stock in series and define all rights, preferences and privileges applicable to such series. This authority may be used to make it more difficult or less economically beneficial to acquire or seek to acquire us.

Special meetings of the stockholders may only be called by our Board of Directors acting pursuant to a resolution approved by the affirmative majority of the entire Board of Directors. Stockholders may not take action by written consent.

The stockholders may, at a special stockholders meeting called for the purpose of removing directors, remove the entire Board of Directors or any lesser number, but only with cause, by a majority vote of the shares entitled to vote at an election of directors.

Warrants

As of August 14, 2015, we had issued and outstanding warrants to purchase up to 34,022,778 common shares, exercisable at prices ranging from $0.50 per share to $1.15 per share.
